1. Represent the fractions: 2/5, 11/5, -8/5 and -3/5 on a number line.

Since, the denominator of each given fraction is 5; divide the space between every pair of two consecutive integers (on the number line) in 5 equal parts. Each part so obtained will represent the fraction 1/5 and the number line obtained will be of the form:

To mark 2/5; move two parts on the right-side of zero.

To mark 11/5; move eleven parts on the right-side of zero.

To mark -8/5; move eight parts on the left-side of zero.

To mark -3/5; move three parts on the left-side of zero.

The following diagram shows markings of fractions 2/5, 11/5, -8/5 and -3/5 on a number line.
